In contrast to the conventional two-stage cam drive system with a 9.52- mm pitch roller chain, a newly developed silent chain with a 6.35-mm pitch has made it possible to achieve a single-stage system. One traditional drawback of silent chains has been wear elongation. In developing the new chain, reliability was substantially improved by identifying the factors causing wear elongation and their effects and also by optimizing the characteristics of the chain components. The application of this single-stage cam drive system to the new QG engine series has resulted in reduced chain noise, a more compact cylinder head and significant weight savings due to the smaller part count and other improvements.
